ROSETTA-ORBITER OSINAC: Comet 67P Images from Extension 3 Mission

OSIRIS Narrow Angle Camera images of comet 67P/Churyumov-Gerasimenko, radiometrically calibrated and geometrically corrected, covering a 14-day period from July to August 2016. This CODMAC level 4 dataset from NASA's Rosetta spacecraft mission includes updated documentation and improved handling of image quality issues. Version 2.0 supersedes previous deliveries with corrections following an external peer review.

Use Cases

• Analyze comet surface reflectance and albedo based on radiometric calibration in W/m^2/sr/nm
• Study geometric features and morphology of comet 67P based on distortion-corrected images
• Assess image data quality and instrument performance based on documented shutter backtravel and readout issues
• Compare comet activity and changes over time based on images from a specific 14-day mission phase

Strengths

• Data is radiometrically calibrated to physical units (W/m^2/sr/nm)
• Images are geometrically distortion corrected and resampled
• Dataset is version 2.0, incorporating corrections from an October 2018 external peer review
• Includes updated documentation with a user guide covering FAQ and image data quality

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data covers only a specific 14-day period in 2016
